Question

I am using .append to fill in an empty list with a string but my item is being appended multiple times. After the first string is appended 5 times and the second string is appended 4 times. Why is this happening?

Here is the code I am using

kw_list_1 = []


def add_kw():
    kw_1 = raw_input('enter your first keyword - ')

    for kw in kw_1:
        kw_list_1.append(kw_1)


    kw_2 = raw_input('enter second keyword - ')

    for kw2 in kw_2:
        kw_list_1.append(kw_2)

    print kw_list_1

For example, if I use 'apple' for kw_1 and 'pear' for kw_2 this is returned

['apple', 'apple', 'apple', 'apple', 'apple', 'pear', 'pear', 'pear', 'pear']

What’s going on here? Is append not the correct way to approach this?

Answer 1

it’s due to the for loop.

  for kw in kw_1:
            kw_list_1.append(kw_1)

just use kw_list_1.append(kw_1) remove the for loop.
